Habitual caffeine consumption moderates the antidepressant effect of dorsomedial intermittent theta-burst transcranial magnetic stimulation.
Study Goal
The researchers aimed to determine whether habitual caffeine consumption enhances the antidepressant effects of intermittent theta-burst stimulation (iTBS) in patients with depressive episodes.
Results Summary
Habitual caffeine consumption was associated with symptom improvement following active iTBS, suggesting caffeine may augment antidepressant effects through adenosine receptor antagonism and dopaminergic pathways.

BACKGROUND: Potentiating current antidepressant treatment is much needed. Based on animal studies, caffeine may augment the effects of currently available antidepressants. OBJECTIVE: Here, we tested whether habitual caffeine consumption moderates the antidepressant effects of repetitive transcranial magnetic stimulation (rTMS) using intermittent theta-burst stimulation (iTBS). METHODS: Forty patients with current depressive episodes were randomized to active iTBS ( RESULTS: Habitual caffeine consumption was associated with symptom improvement following active iTBS ( CONCLUSION: Habitual caffeine consumption moderated the antidepressant effect of dorsomedial iTBS, consistent with caffeine improving antidepressant pharmacological treatments in animals. Caffeine is an antagonist of adenosine receptors and may enhance antidepressant effects through downstream dopaminergic targets.
